New home owner here and I have been searching the internet to figure out what weed this is and how to get rid of this. Can anyone tell me what this weed is and what is the best way to get rid of it? I know there is another weed that closes it's leaves when touched and bears purplish round flowers. This is NOT that! The leaves may appear closed because I plucked them out of the lawn. These are spreading rapidly from one corner of my lawn to other. I am in South texas if that helps. All the pictures I saw in internet are hard to distinguish probably because I am a newbie.
